SIMILARITY. 1S2 SIMMONS COLLEGE. Hence, central symmetry is a special case of similar figures in perspective. The term centre of similitude is due to Euler. (See Stmmetkt.) Some of the principal propositions of Similarity THREE SIMILAR TETRAHEDRA. are: ISvo triangles are similar if they have two angles of one equal to two angles of the other, respectively. Mutually equiangular triangles are similar. If two triangles have the sides of the THREE SIMILAR QUADRILATERALS. one respectively parallel or perpendicular to the sides of the other, they are similar. If two triangles have one angle of the one equal to one angle of the other, and the including sides pro- portional, the triangles are similar. If two tri- angles have their sides proportional, they are similar. If two polygons are mutually equi- angular and have their corresponding sides pro- portional, they are similar. Areas of similar polygons are proportional to the squares of the corresponding sides. Volumes of similar solids are proportional to the cubes of their like di- mensions.

The capital of a district of the Punjab, British India, on a ridge of the Hima- layas, 7000 feet above the sea, 170 miles north of Delhi (Map: India, C 2).

In 1881, his healtli failing, he returned to the United States; but in 1887, drawn again to Japan, he made a systematic study of Japanese feudal institutions.

SIMMONS COLLEGE. An institution at Boston, Mass., incorporated in 1899 and opened in 1902. It was established in accordance with the provisions of the will of John Simmons, a Boston merchant (died 1870), to afford women a practical education in such branches of art, science, and industry as would best enable them to earn an independent livelihood. In 1903 the number of students in the two classes that had been received was 280, and the number of regu- lar instructors 40, in addition to special lectur- ers. The first class numbered 146 and .the fac- ulty 25. The departments of instruction first organized comprised household economics, sec- retarial work, library training, and preparatory for teaching, for medicine, or for nursing. Since
